Abstract

PCT No. PCT/SI95/00006 Sec. 371 Date Sep. 20, 1996 Sec. 102(e) Date Sep. 20, 1996 PCT Filed Mar. 20, 1995 PCT Pub. No. WO95/25964 PCT Pub. Date Sep. 28, 1995According to the method for controlling the grinding of mineral raw materials, at a predetermined value i* of the impregnation level to which the fines of the specimen are impregnated by the impregnating agent, the effective spin-lattice relaxation time of the impregnating agent protons is measured. Each time the parameters of the grinding process are set so that the approximation s'NMR for the specific surface area of the fines will attain a prescribed value soNMR. Each time the residue percentage of the fines retained on a sieve is determined and at the onset of an increase of the residue percentage the grinding is controlled so that a subsequent agglomeration of fines particles is suppressed. The fines are impregnated by a liquid impregnanting agent comprising hydrogen atoms. In the appliance of the invention the measuring and control unit comprises a measuring unit consisting of a measuring vessel and a digital automatic analytical balance, which are preferably situated in vacuum tank, and a nuclear magnetic resonance spectrometer with coherent pulses. According to the proposed method the grinding control is based on a detected agglomeration of fine particles of the fines.
